f .IARvIs ooMPANY, or GRAND RAPIDS, MICHIGAN CLOSURE FOR RADIATORS ANDTHE LIKE Application filed December 18, A1929. 'Serial No. 414,890.

The main object of this invention is to provide a closure for radiatorswhich is well adapted for use on radiators having the types of necks nowin quite extensive use and one which is securely retained upon the neck.

A further object is to provide a structure having these advantages whichmay be very quickly applied to or mounted upon the neck.

Objects pertaining to details and economies of my invention willdefinitely appear from the description to follow. The invention isdefined in the claims. i

A structure which embodies the features of my invention is clearlyillustrated in the accompanying drawing, in which:

Fig. 1 is a front perspective view of a radiator cap structure embodyingthe features of my invention.

Fig. 2 is a fragmentary view partially in vertical section on line 22 ofFigs. l and 4.

Fig. 3 is an inverted view of the closure removed from the radiatorneck.

Fig. 4: is a plan view of the neck, the coacting relation of theclosure, keeper lugs and locking pin being indicated by dotted lines.

In the embodiment illustrated, 1 represents the radiator shell of amotor vehicle and 2 the radiator having a filling neck 3 projectingthrough the radiator shell. The neck is provided with an inturned flange4 providing a seat for the gasket or packing 5. On the edge of theflange I form segmental, opposed cammed keepers 6 having depending stops7 at corresponding ends thereof.

The closure body member 8 is ohambered to receive the projecting end ofthe neck and rest upon the shell. The gasket 5 is clamped between thebody member and the neck.

The body member 8 is provided with an annular depending flange-likelatch member 9 having keeper engaging lugs l() struck outwardlytherefrom and engageable with the keepers by a rotative movement of thebody member on the neck, thereby forcing the body member downwardly intoclamping engage ment with the gasket 5 and firmly seating it on theshell.

The body member is provided with an upwardly facing gasket seat 11 forthe cap gasket 12. The locking pin 13 is arranged through the bottom ofthe gasket seat to engage the stop end of one of the keepers 6; that is,it engages the end of the keeper in opposed relation to the lug, therebylocking the body member against rotative movement on the neck andpreventing its removal without removing the locking pin.

The cap 14 is provided with a vertical pivotl 15 mounted for verticaland rotative movement, the cap structure illustrated being that` of thecopending application of Frederick C. Ruppel and Michael B. Andrie. Asthe particulardetails of the cap do not constitute a part of thisinvention, they are not illustrated herein.

f My improved closure is wellY adapted for use on radiator necks of thetype now in eX- tensive use, that is, radiator Vnecks having cammedkeepers with which-the cap is directly engaged by a rotative movement. l

My improvements provide a structure in which the 'capis locked to thevehicle and an effective finish is provided for the shell.

I have illustrated and described my improvements ina Very practicalembodiment thereof. I have not attempted to illustrate or describe otheradaptations or modifica* Vtions as it is believed that this disclosurewill neck and engaging said gasket thereon yand having an annular latchmember depending within the neck and provided with keeper engaging lugsstruck outwardly therefrom, said body member being provided lwith anannular upwardly facing gasket seat, a locking pin arranged through thebottom of said upwardly facing gasket seat i of said closure body memberto engage the stop end of one of said keepers whereby the said closurebody .mem-

no j

ber is locked against rotation on said neck, and a cap mounted on saidbody member.

2. The combination of a neck having oppositely disposed segmental cammedkeepers, said keepers having .stops at corresponding ends thereof, aclosure body member chambered to receive the end of said neck and havingan annular latch member depending within the neck and provided withkeeper engaging lugs struck outwardly therefrom, a locking pin arrangedto lie in the path of and engage the stop end of one of said keeperswhereby the said closure body member is positively locked againstrotation onsaid neck, and a cap mounted on said body member.

.3. 'Thecombination of a neck having segmental cannned keepers, saidkeepers having stops at corresponding ends thereof, a gasket arranged onsaid neck, a closure member engaging said gasket on said neck andprovided with keeper engaging lugs coacting with said keepers on saidneck, a locking pin on .said body member lying inthe path of andengaging the stop end of one 'of said keepers whereby the closure bodymember is positively locked upon the neck, and a cap mounted on saidbody member. p

4. The combination of a neck provided with keepers, a closure bodymember provided with lugs engageable with said keepers by rotatitvemovement of the body member, a gasket interposed between said bodymember and neck, said keepers being cammed sothat the body member isclamped upon the gasket by the engaging movement thereof, a locking pinon said body member'lying in the path of and engaging one of saidkeepers in opposed relation to one of said body member lugs whereby thebody member is positively locked against rotation upon the neck, and acap on said body member.

5. The combination of a neck provided with keepers, a closure bodymember engageable with said keepers by rotative movementof the bodymember, said body member having an upwardly facing gasket seat, alocking pin arranged through the bottom of said upwardly facing gasketseat to lie in the path of andengage one of said keepers whereby saidclosure body member is positively locked against rotation on said neck,a gasket arranged in said gasket seat over said pin, and a cap mountedon said body member to coact with said gasket. f

6. The combination of a neck provided with keepers having stops atcorresponding ends thereof, a closure body member provided with keeperengaging lugs coacting with said keepers on said neck, a locking pin onsaid body member lying in the path of and engaging the stop end of oneof said keepers whereby the closure body y member is positively locked'upon the neck, and a capk mounted on said body member.
